The Mediterranean diet is commonly proposed as a major modifiable protective factor that may delay cognitive impairment in the elderly. The aim of the study was to investigate the cross-sectional association of adherence to the Mediterranean diet with cognitive abilities in a younger Greek population. A total of 1201 healthy adults aged 21-77 years (mean: 47.8) from the Epirus Health Study cohort were included in the analysis. Adherence to the Mediterranean diet was measured using the 14-point Mediterranean Diet Adherence Screener (MEDAS) and cognition was measured using the Trail Making Test, the Verbal Fluency test and the Logical Memory test. Statistical analysis was performed using multiple linear regression models adjusted for age, sex, education, body mass index, smoking status, alcohol consumption and physical activity. Overall, no association was found between the MEDAS score and cognitive tests, which could be explained by the young mean age and high level of education of the participants. Future studies should target young and middle-aged individuals to gain further understanding of the association between Mediterranean diet and cognition in this age group.
地中海饮食通常被认为是一种主要的可改变的保护因素,可以延缓老年人的认知障碍。本研究的目的是调查在年轻的希腊人群中,地中海饮食的依从性与认知能力之间的横断面相关性。共有 1201 名年龄在 21-77 岁(平均年龄:47.8 岁)的伊庇鲁斯健康研究队列的健康成年人被纳入分析。采用 14 分地中海饮食依从性筛查器(MEDAS)来衡量地中海饮食的依从性,采用连线测试、词语流畅性测试和逻辑记忆测试来衡量认知能力。使用调整年龄、性别、教育程度、体重指数、吸烟状况、饮酒和身体活动的多线性回归模型进行统计分析。总体而言,MEDAS 评分与认知测试之间没有关联,这可以用参与者的年轻平均年龄和高教育程度来解释。未来的研究应该针对年轻和中年个体,以进一步了解这一年龄组中地中海饮食与认知之间的关联。
